How big is the 92 mm throttle body?

The FAST 92-mm throttle body measured 3.540 inches in diameter, considerably smaller than the nearly 3.70-inch opening in the LS3 intake. We couldn’t help but wonder if there was more power to be had from a larger throttle body?

Is the intake of the L98 the same as the L76?

The L98 had the same intake as the L76 and was equipped with a 90mm Silver blade throttle body up to mid-2009. The blade rotates the same direction as the LS2, but opposite of the LS3 with its Gold throttle blade. This intake isn’t as good as the LS3, so the LS3 is a common swap.

Again, this was done just to satisfy my own curiosity, so bare with me. The throttle body you see below is made by TPIS.
